Three more retractions for weight loss surgeon Edward Shang for making up data

Edward Shang, the weight loss surgeon who lost his job at the University of Leipzig in May after it was revealed that he had made up most, if not all, of the patients in his research studies at the University of Mannheim, has retracted three more papers.

Here’s the notice, which is a bit, um, lean, given what we know about the case: Continue reading Three more retractions for weight loss surgeon Edward Shang for making up data

Updated: Ski resort paper hits a (media) mogul and gets retracted

With temperatures at Retraction Watch’s New York HQ threatening to break 100 degrees today — that’s nearly 38 degrees Celsius for those of you in the rest of the world — what better way to take our minds off the heat than by writing about than skiing?

Lucky for us, the author of a paper in the Journal of Maps about new ways to create ski resort maps — aka the “Breckenridge schematic map” — has retracted it. Here’s the notice: Continue reading Updated: Ski resort paper hits a (media) mogul and gets retracted

Tell-tale hearts: Cardiology journals retract redundant articles

The European Journal of Cardiothoracic Surgery has retracted a 2007 article by Chinese researchers after the senior author decided he liked the data so nice he’d publish them twice. And he appears to have done so without the knowledge of the corresponding author.

Here’s the notice for the paper, titled “Open-heart surgery in patients with liver cirrhosis”: Continue reading Tell-tale hearts: Cardiology journals retract redundant articles

Shikeagi Kato, who resigned post in March, retracts Nature paper

Shikeagi Kato, an endocrinologist formerly of the University of Tokyo who resigned on March 31 amidst an investigation into his work, has retracted another paper, this one in Nature.

Here’s the notice for “DNA demethylation for hormone-induced transcriptional derepression,” which was the subject of a correction last October: Continue reading Shikeagi Kato, who resigned post in March, retracts Nature paper

Biologists delete paper from literature after realizing they’d deleted too many genes

Researchers deleted more genes than they bargained for in a Drosophila strain, a mistake that resulted in a retraction of a paper from 2007.

Ron Wides, a biologist specializing in pattern development at Bar-Ilan University, Israel, and colleagues have retracted a paper published in Mechanisms of Development after his lab found that their technique to delete the Ten-a gene ended up deleting other nearby genes, too.

It was deletions of other genes, and not Ten-a, that killed the fruit flies, Wides concluded. His group had also concluded, erroneously, that Ten-a is what’s known as a “pair-rule” gene. Fruit fly embryos develop in stacked segments, like tubes of Pringles; pair-rule genes guide the development of alternating segments. Those other loci, and not Ten-a, caused lethality and caused the flies to develop improperly early, Wides concluded.

Korean stem cell investigation expands to another researcher, and more papers

Last month, we brought you the story of Soo-Kyung Kang, a Seoul National University stem cell researcher who has now retracted four papers amidst questions about image manipulation in a total of 14 studies. That story has drawn a great deal of attention in Korea, with comparisons to the Woo-Suk Hwang scandal, and has even led to a profile of Retraction Watch in the Seoul Daily, one of Korea’s largest newspapers.

We’ve now learned that the investigation has grown to 25 papers after an anonymous whistleblower warned about possible data fabrications in another paper by Kang, an associate professor of veterinary biotechnology, and Kyung-Sun Kang, director of the Adult Stem Cell Research Center in the same department (but no relation). And Soo-Kyung Kang was investigated in 2010, according to the Korea Herald.

The researchers’ labs are also under lockdown Continue reading Korean stem cell investigation expands to another researcher, and more papers

Former Millennium Villages Project staffer responds to critical Nature editorial

Last week, we wrote about a correction of a heavily criticized paper in The Lancet by the Millennium Villages Project, a large aid program. Paul Pronyk, director of monitoring and evaluation at Columbia University’s Center for Global Health and Economic Development, which runs the Project, left his job shortly after writing an explanatory letter that accompanied the correction.

That correction had come after a letter to The Lancet, but also after Nature had raised issues in an editorial. Nature’s editorial concluded: Continue reading Former Millennium Villages Project staffer responds to critical Nature editorial

Premature delivery? Paper on rapid assay for ruptured placenta pulled for “mishandling” of tests

The other day we brought you the story (well, not quite a STORY) of a group of researchers who had to retract a paper in the Journal of Computational Chemistry because of a “computation error.” We still don’t know what that means.
